IMPROVEMENT IN ENVELOPES.

The Schedule freferred to in, these Letters Patent and making part ofthe same.

To all whom 'it may concern:

Be it known that 1, G. 1). HACHENBEBG, of Hudson, in the county ofColumbia, and State of New York,`have invented a new and usefulImprovement in Paper Envelopes; and 1 do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention relates toa new and improved meth\ od of formingenvelopes for letters and for official and professional enclosures, aswell as for paper packages or parcels; and

It consist-s in a fold formed on one or more of the edges of theenvelope, in such a manner that the fold so made may be readily tornoli', and the envelope thereby be opened, as will be hereinafter morefully more folds or thicknesses, as seen in fig. 2.

This fold may be pressed down tightly on to the side of the envelope, sothat the projection will he but slight, and it may be formed on eitheredge, and on more than one of the edges of the envelope, if desired Inopening the envelope, the fold is readily raised bythe thumb-nail, whenit is easily torn off clean from the envelope, as the fracture willfollow the line of the fold in all cases, thus abrding a most convenientand ready inea-ns tin' gaining access to the contents of the envelope.

The advantages of this method of forming envelopes and other papercoverings are, that the fold forms a part of the envelope or covering,is cheaply made, and attended with less trouble in opening the envelopethan any method heretofore discovered.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- As a new articleof manufacture, the envelope herein described, provided with the fold A,substantially as set forth for the purpose specified.
